The caretaker manager says those higher up the club have promised there will be money spent in the transfer window.
The Magpies were beaten 3-0 by relegation-threatened Leicester City on Saturday afternoon, their eighth consecutive defeat, leaving them just two points clear of the relegation zone.
It was yet another bad performance from the side in a run that has seen them slide down the table. That has led to criticism of Carver and his playing staff after a string of indifferent displays.
Carver is unlikely to remain as manager in the summer, but he has revealed that those higher up the hierarchy have promised there will be signings to bolster the squad in the summer.
“They’ve promised me they’re going to invest money,” he said.
“It doesn’t always give you success but it gives you a head start. We could possibly break into the top eight but this summer is going to be a big one for us.”
The current predicament of the club is a far cry from the halcyon days of the past, with them being Premier League title challengers under Kevin Keegan in the 90’s and then Champions League hopefuls under Sir Bobby Robson.
Carver was part of the staff during Robson’s highly impressive time in charge, and was keen to highlight the differences between those sides and the one currently at his disposal.
“We had a lot of big name players,” he added.
“We had the nucleus of a British side and some top players along with Sir Bobby,
"But we also had a group of people who were prepared to spend money. Freddie Shepherd, who was chairman at the time, spent money on a team worthy of finishing in the top four.”
